Abstract: ABSTRACT OF THE DISCLOSURE         The invention is a fireproof material suitable for use in foundry runner bricks.  The material comprises from 20 to 30% by weight of A?2O3, from 60 to 70% by weight of SiO2 and from 1.5 to 10% by weight of an additive oxide which is CaO or MgO. It may also contain up to 10% by weight of TiO2, Fe2O3 or Na2O.          In contact with molten steel there is generated slag which dissolves impurities in the steel.  The slag containing the impurities is readily separable from the steel.

Abstract: ABSTRACT 3-D television without glasses having horizontal parallax and operating over standard single channel bandwidth is implemented by using two television cam-eras aligned in the same plane, a 2:1 bandwidth compres-sion and a receiver that processes the two views one scan line at a time using successive element correlation within common scan lines to synthesize N views in-between the two received views. The television receiver/ projector contains an optical scanner with a central projection lamp, N + 2 small full frame Charge Couple Device Liquid Crystal Light Valve (CCDLCLV) television modulation array surfaces and is driven by N + 2 views of the scene.  N + 2 views are sequentially projected by the optical scanner to a semi-specular screen that returns all projected light to a horizontally moving vertical aerial exit slit (having no physical properties) resulting in the accurate reconstruction of continuous scene horizontal parallax for simultaneous view by several observers.

Abstract: AIR EFFICIENT ATOMIZING SPRAY NOZZLE                 ABSTRACT OF THE DISCLOSURE        The invention comprises an atomizing spray nozzle containing multiple restrictions to the flow of an air and water mixture through the nozzle created by contours in the stem in relation to the orifice and having a whirl chamber in the nozzle body where injected air induces disturbances in the liquid to create effective atomization prior to the first restriction which creates a negative pressure be-yond the restriction and which is repeated at additional restrictions thus resulting in a repeat-ed depressurization and sudden expansion to obtain a finely atomized mixture before reaching the orifice, with a final restriction at an outlet that may take the form for a flat spray or one for a narrow round spray.

Abstract: Abstract TREATMENT OF FUEL PELLETS    A method of treating a nuclear reactor fuel pellet which has been irradiated and is at least partially depleted of its initial fissile material content to substantially reduce the amount of fuel which would have to be reprocessed before it could be reused.  The pellet is pulverized to a median particle size of less than about 300 microns and thereafter is separated into two fractions by size.  In accordance with the present invention, it has been found that one of said fractions will contain a significantly greater proportion of the fissile content of the pellet than the other of said fractions.  The fissile-rich fraction is suitable for reforming into pellets for use in a nuclear reactor with little or no further enrichment required.  The method of the present invention is applicable to the metallic, oxide, and carboxide forms of nuclear reactor fuels such as uranium and thorium, which have been in service in a light water reactor or a fast breeder reactor.

Abstract: SUPERCONDUCTING SOLITON DEVICES     ABSTRACT            Josephson solitons are steered along selected paths in response to applied control signals, the output path chosen being dependent solely upon the presence and absence of these control signals.  An input Josephson transmission line is provided along which the Josephson soliton travels.  This input line inter-sects with two output Josephson transmission lines. Bias currents of opposite polarity in the output transmission lines are used to steer the soliton in-to a selected one of the output lines.  At the inter-section of the input line and the output lines an isolating resistor is located.  This resistor dissi-pates the anti-soliton created at the intersection and provides isolation between the input and the out-put of the device.  In a preferred embodiment, one electrode of the input and output Josephson trans-mission lines can be comprised of a common super-conductor and the isolating resistor can be located between the other electrodes of the output trans-mission line.  Path selection is determined solely by the control signal, and is not dependent upon internal damping of the device or the choice of boundary conditions at the intersections.

Abstract: Abstract A hydraulic piston cylinder device comprising a cylinder (1), a piston (2) dividing the cylinder into two cylinder spaces (A and B), and valve elements (7,9) between the cylinder spaces (A and B) and the respective pressure medium pipes (11,12).  The problem is to accomplish a hydraulic piston cylinder device in which the pressing or tractive force of the cylinder is maintained even if the external pressure led into the cylinder would stop.  To solve this problem, the piston (2) is elastically compressible by the pressure of the cylinder (1) and the valve members (7,9) are coupled to each other so that when one of the valve members (7 or 9) is closed the other (9 or 7) cannot be closed. The piston is divided in the axial direction into two successive parts (21,22) spaced from each other, between which parts there is elastic material (3).

Abstract: ABSTRACT OF THE DISCLOSURE:     Fully and partially aryl amine terminated polysulfide polymers and processes for their preparation and use are disclosed.  The fully aryl amine terminated products are curable with isocyanates to high molecular weight polymers and are thus useful in molding and casting as well as in sealants.  The partially aryl amine terminated polymers may be further reacted with polyisocyanates to form thiol terminated polysulfide polymers containing urea chain segments. These compounds are curable in the fashion of standard polysulfide polymers to form firmer polymers.  The partially aryl amine terminated polymers may be also chain extended with isocyanate terminated urethane prepolymers.  These block copolymers may be cured by standard SH terminated polysulfide polymer cure methods to prepare sealants of exceptional resiliency and weather resistance.

Abstract: ABSTRACT OF THE DISCLOSURE            A swimming pool wall, for placement in an excavation, is made up of a series of bendable plates having only vertical flanges for stiffening while permitting shaping the wall to a selected outline.  A resilient coping strip embranes the upper edge of the wall and houses a rigid metal bar to retain the upper edge of the wall in the desired configuration while other braces, at the lower edge of the wall extend from the plates to the outer edge portions of the flanges to securely maintain the lower edge of the wall in the desired configuration.  Vertical Z-shaped bars are secured to certain of the plates to further stiffen them and further braces, secured to the flanges, ex-tend diagonally upward into a concrete apron, selected ones of the diagonal braces carrying a form plate for defining the outer edge of the apron.  Rigid bars are used to hold corner plates to a desired curvature during assembly of the pool wall and its placement in the excavation.  After back-filling and forming the apron, those bars are removed.
